Referring to the drawings and initially to FIGS. 1-5, an exercisingdevice 1 in accordance with the preferred embodiment of the presentinvention comprises a support frame 11, a pivot unit 12, a footrest 13,a backrest bar 14, and two armrests 15.

The support frame 11 is substantially inverted V-shaped, and includes afront stand 111, a rear stand 112 pivotally connected with the frontstand 111, and a pivot shaft 113 pivotally mounted between the frontstand 111 and the rear stand 112. The front stand 111 of the supportframe 11 is substantially U-shaped, and has an upper end provided with atube 114 having a mediate portion formed with an opening 115. The rearstand 112 of the support frame 11 is substantially U-shaped, and has anupper end provided with two opposite mounting tubes 116 each mounted onthe tube 114 of the front stand 111 and provided with a crossbar 117located below the two mounting tubes 116. The crossbar 117 has a mediateportion provided with a stop block 119. The rear stand 112 of thesupport frame 11 is provided with two opposite mounting sleeves 118. Thepivot shaft 113 of the support frame 11 is extended through the twomounting tubes 116 of the rear stand 112 and the tube 114 of the frontstand 111.

The pivot unit 12 is pivotally mounted on the support frame 11, andincludes an operation lever 121 pivotally mounted on the pivot shaft 113of the support frame 11, and a threaded swivel shaft 124 rotatablymounted on the operation lever 121. The operation lever 121 of the pivotunit 12 is located in the opening 115 of the tube 114 of the front stand111 and is formed with a transverse hole 121 b for passage of the pivotshaft 113 of the support frame 11. The operation lever 121 of the pivotunit 12 has a mediate portion formed with a shaft hole 121 a for passageof the swivel shaft 124.

The footrest 13 is mounted on the pivot unit 12 and includes a fixedsection 131 having a first end secured on an upper end of the swivelshaft 124 of the pivot unit 12 to rotate therewith, and a movablesection 132 having a first end movably mounted in the fixed section 131and a second end protruded outward from a second end of the fixedsection 131. The footrest 13 further includes a seat plate 134 securedon the first end of the fixed section 131. The footrest 13 furtherincludes an arc-shaped connecting seat 138 secured on the second end ofthe movable section 132, and a footrest seat 133 secured on theconnecting seat 138 by a plurality of screw members 139. The second endof the fixed section 131 of the footrest 13 has a top formed with apositioning hole 135, the movable section 132 of the footrest 13 has atop formed with a plurality of threaded adjusting holes 137, and thefootrest 13 further includes a threaded adjusting member 136 extendedthrough the positioning hole 135 of the fixed section 131 and screwedinto a respective one of the adjusting holes 137 of the movable section132.

The pivot unit 12 further includes an upper bearing 122 mounted on theswivel shaft 124 and located between the fixed section 131 of thefootrest 13 and the operation lever 121 of the pivot unit 12, a nut 125screwed on a lower end of the swivel shaft 124, and a lower bearing 123mounted on the swivel shaft 124 and located between the operation lever121 of the pivot unit 12 and the nut 125.

Each of the upper bearing 122 and the lower bearing 123 includes amounting ring d, a fixing race f secured on the mounting ring d, and aball ring e mounted between the mounting ring d and the fixing race f.

The operation lever 121 of the pivot unit 12 has a first end formed witha through hole 121 c, the first end of the fixed section 131 has abottom formed with a threaded locking hole 1310, and the pivot unit 12further includes a threaded fixing member 126 extended through thethrough hole 121 c of the operation lever 121 and screwed into thelocking hole 1310 of the fixed section 131, so that the fixed section131 of the footrest 13 is fixed on the operation lever 121 of the pivotunit 12. The operation lever 121 of the pivot unit 12 has a second endthat can be pivoted to abut the stop block 119 of the support frame 11.

The backrest bar 14 is substantially L-shaped, and has a horizontalsection secured on the fixed section 131 of the footrest 13 by a fixingmember 142 and a vertical section provided with a backrest 141.

Each of the two armrests 15 is mounted on the rear stand 112 of thesupport frame 11 and has a lower end inserted into a respective one ofthe two mounting sleeves 118.

In operation, referring to FIGS. 6 and 7 with reference to FIGS. 1-5,the fixing member 126 of the pivot unit 12 is unscrewed from the lockinghole 1310 of the fixed section 131, so that the fixed section 131 of thefootrest 13 is released from the operation lever 121 of the pivot unit12. Then, the swivel shaft 124 can be rotated on the operation lever 121of the pivot unit 12, so that the fixed section 131 and the seat plate134 of the footrest 13 can be swiveled on the operation lever 121 of thepivot unit 12 the swivel shaft 124, thereby achieving the effect ofexercising the user's feet and waist.

Referring to FIG. 8 with reference to FIGS. 1-5, the fixing member 126of the pivot unit 12 is screwed into the locking hole 1310 of the fixedsection 131, so that the fixed section 131 of the footrest 13 is fixedon and combined with the operation lever 121 of the pivot unit 12. Thus,the fixed section 131 and the seat plate 134 of the footrest 13 and theoperation lever 121 of the pivot unit 12 can be pivoted about the pivotshaft 113 of the support frame 11, thereby achieving the effect ofexercising the user's feet, back and waist.

Referring to FIG. 9 with reference to FIGS. 1-5, the backrest bar 14 isremoved from the fixed section 131 of the footrest 13. Then, the fixedsection 131 and the seat plate 134 of the footrest 13 and the operationlever 121 of the pivot unit 12 can be pivoted about the pivot shaft 113of the support frame 11 until the second end of the operation lever 121of the pivot unit 12 is rested on the stop block 119 of the supportframe 11, so that the footrest seat 133 of the footrest 13 is locatedhigher than the pivot shaft 113 of the support frame 11, therebyfacilitating the user practicing the skill of upside down.
